Mbh 5.16.2

“Salya continued, ‘Then Agni entered the waters including seas and tiny ponds, and came to that reservoir, where, O best of Bharata’s race, while searching the lotus flowers, he saw the king of the gods lying within the fibres of a lotus-stalk. And soon coming back, he informed Vrihaspati how Indra had taken refuge in the fibres of a lotus-stalk, assuming a minute form. Then Vrihaspati, accompanied by the gods, the saints and the Gandharvas, went and glorified the slayer of Vala by referring to his former deeds. And he said, “O Indra, the great Asura Namuchi was killed by thee; and those two Asuras also of terrible strength, viz., Samvara and Vala. Wax strong, O performer of a hundred sacrifices, and slay all thy foes. Rise, O Indra! Behold, here are assembled the gods and the saints. O Indra, O great lord, by slaying Asuras, thou hast delivered the worlds. Having got the froth of waters, strengthened with Vishnu’s energy, thou formerly slew Vritra. Thou art the refuge of all creatures and art adorable. There is no being equal to thee. All the creatures, O Indra, are supported by thee. Thou didst build the greatness of the gods. Deliver all, together with the worlds by assuming thy strength, O great Indra.” And thus glorified, Indra increased little by little; and having assumed his own form, he waxed strong and spoke to the preceptor Vrihaspati standing before. And he said, “What business of yours yet remaineth; the great Asuras, son of Twashtri, hath been killed; and Vritra also, whose form was exceedingly big and who destroyed the worlds.”
